Hidden Valley Trailhead is located in the north end of Hidden Valley (near Jean, NV), which is on the southwest edge of Sloan Canyon National Conservation Area. Access to this trailhead requires a 2WD-HC vehicle or a carefully driven sedan under good conditions.

From town, drive south on Interstate-15 to the Sloan exit. Exit the highway, turn east (left), and cross under the interstate to a T-intersection, which is Las Vegas Blvd. Turn right and drive south 6.3 miles to Southern Nevada Liteweight Road, on the left.

Turn left and drive east 4.4 miles to Hidden Valley Road, a narrow dirt road on the left. Turn left drive north 5 miles following carsonite signs to the trailhead (Site 1206). Park here; this is the Hidden Valley Trailhead. Link to trailhead map.

This trailhead provides access to BLM 300 Trail and Poppy Guzzler Route (both with access to Sloan Canyon Petroglyph Gallery), and myriad off-trail routes in the North McCullough Wilderness Area.
